ELECTRIC-LAMP BRACKET.

SPECIFICATION forming part of Letters Patent No. 444,466, dated January13, 1891.

Application filed May 19,1890. Serial No. 852,338. (No model) To allwhom it may concern.-

Be it known that I, THOMAS CARPENTER SMITH, a subject of the Queen ofGreat Britain and Ireland, and a resident of Philadelphia, Pennsylvania,Uni ted States of America, have invented a certain new and usefulImprovement in Electric Lamp Brackets, of which the following is a full,clear, and exact specification.

My invention relates to lamp-brackets, particularly such as are used onthe street for the support of incandescent lamps for municipal lightingand the like, and has for its object to provide a convenient and simplebracket of the kind described. It is illustrated in the accompanyingdrawings, wherein Figure 1 is a perspective view of the bracket withoutthe lamp attachment, and Fig. 2 is a cross-section through the same withthe lamp applied.

Like parts are indicated by the same letter in both the figures.

A is the post upon which the bracket is to be secured.

K K are the conductors leading from the main conductors to theinsulators O O and thence to the lamp. These insulators are supported onthe arms 0 O, which extend from the central portion P, which arms areprovided with rear vertical ribs R R, between which is a space, wherebythe plate P, and thus the bracket, will be securely fastened to thepost- A.

S is a thimble projecting from the plate P and screw-threaded atitsinnerend, in which thimble is screw-threaded the pipe T, to the outer end ofwhich is secured the lamp V with the shade IV.

U is an aperture in the lower portion of the pipe T, through which theconductors K K are admitted into the tube or pipe T, within which theypass to the lamp. This makes a strong and secure bracket, in which thecondoctors are concealed and protected at the point where they approachand enter the lamp.

The use and operation of my invention are sufficiently understood fromthe foregoing description. It might be modified somewhat withoutdeparting from the spirit of my in vention. The lamp-fixture and bracketare combined in a very simple manner, and the conductors thus brought tothe insulators O O in close proximity to the lamp are introduced intothe tube or pipe T, and thus carried in a secure manner to the lampitself.

Having thus described my invention, whatI claim, and desire to secure byLetters Patent,

is as follows:

1. A bracket consisting of a plate with a projecting thinible thereon, apipe secured on such thimble and having a hole in one side thereof andadapted to receive the lamp-fire ture at its other end, and insulatorson such plate, so that the conductors may pass from such insulatorsthrough the hole into the pipe and thence to the lamp.

2. A bracket consisting of a plate adapted to be secured to the post,arms and insulators on such plate, a lamp-fixture, and a hollow pipeholding the same at one end and secured to the plate at the other, saidpipe having an aperture into which the conductors from the insulatorsmay pass.

3. In a bracket, the combination of a central plate, flanged to engagethe post, with arms and insulators thereon, and a screwthreaded portionto receive the lamp-support.

4.. In a bracket, the combination of a cen tral plate, flanged to engagethe post, with arms and insulators thereon, and a thimble projectingfrom such plate.

5. In a bracket, the combination of a eeutral plate, flanged to engagethe post, with arms and insulators thereon, and a thimble projectingfrom such plate, said thimble screw-threaded internally, in combinationwitha pipe screw-threaded into such thimble to receive the conductorsfrom the insulators.
